Question

Define resolving power of an astronomical refracting telescope and write expression for it in normal adjustment.Assume that light of wave length 6000Å is coming from a star, what is the limit of resolution of a telescope whose objective has a diameter of 2.54m? ​

Answer 1

Answer:

Resolving Power

RP = a/1.22lemda

a - Diameter

lemda - wavelength

RP = 3.47 × 10^6
